ranged a piuraiity 01 magma slots one adjacent each 0;? the straigigai sides cf the 'pdlygon. At ihe edge at" each 01} 1e p01ygmm plates is pz'evialed plurality of 0u1tthe two plates 0 0", each of which has only three sides of the octagon-shaped member a. The. member 0 is provided with overturned flanges c and with slots 0*. The longitudinal members are connected therewith-in the same manner as described with reference to the other joint-members, by engagement of their ends in the slots 0. Two of such members a areshown in Fig. 8, one at each of the lower corners thereof.

The auxiliary member e, shown in Fig. 4, comprises a U-shaped body-portion, each wing of the U having three sides 8, 6, e the upper andlower of which are tapered toward the central side or edge 6 At said central edge e is located an overturned flange re. Adjacent each of the sides are slots 6 to receive the ends of the longitudinal members. At top and bottom the memher 6 is provided with transverse lugs e, a respectively. The height of the lJ-shaped member, that is to say, the distance between the lugs e, e is such that when the member e is applied to the face of either of the plates of the members a and b the U-shaped member 6 may he slid sidewise into position with said lugsf e gle beneath and retained by the flanges o e plate. Thus, in Fig. 7, the member 6 is shown with its upper lug e engaged with the upper flanged of the plate a, and its lower flange e engaged with the lower flange a of the plate a. The U-shaped member 6 is thereby retained frictionally with its wings e", 6 projecting outwardly perpendicular to the plane of the member a. Then by inserting in the slots e of said member 6 the ends of longitudinal members a, it is obvious that these longitutudinal members extend in a plane at right angles to that of the remainder of the structure. The ends of said longitudinal members are shown at e, e, and c in Fig. 7, the member 6 extending horizontally,while the member a is inclined upwardly, and

the member 6 is inclined downwardly, but

all in a plane at 90 to the plane of the connectingaember a. In like manner the member 6 may be connected with the member b at the edge of the striicture, and

thereby an extension of the structure in a plane at right angles to the part first constructed is obtained at its edge. The memher a has no dimension between opposed overturned flangescorresponding with the distance between the lugs e, e, and it is therefore not possible to connect the memher a with the member a, and it is necessary to provide a special auxiliary member for extending the structure at right angles from the joint-member 0. Such an auxiliary joint-member is shown in Fig. 6. It is U- shaped and provided with two lugs g 9 The wings g", 9 have two sides or edges g respectively, one inclined and the other vertical. Slots 9 are arranged adjacent their bent ends into the slots 9 in the manner previously described.

The joint-members described pgovide means for constructing a framing or other mechanical building construction in one plane and in a direction at right angles thereto. The auxiliary member f (Fig; 5)

members described, provides means for extending the structure at an angle of 45 from any given plane thereof. For this purpose the member e is provided with overturned lugs e, e and a member 7' is provided having two angularly-disposed sides 7', f and triangular sides f 7" applied thereto. In each of the triangular sides is a slot f and at the outer ends of the sides 7, f are lugs f, 7" respectively. This memher 7 is inserted in the position clearly shown in Fig. 7 namely, horizontally disposed with its lug f en aging the over turned flange a of the nilzmber a, and its lug f? engaging the overturned flange a of the member e, whereby the member 7 is frictionally held. A. longitudinal member has its ends f inserted in the slots f", as shown in Figs. 7 and 9, whereby said member extends at an angle of 45 to the plane through the member a and 45 to the plane through the member 6. A diagonal bracing of the structure may be thereby obtained, which greatly strengthens the same, An ad ditionalvariety of pleasing forms of construction is also permitted by the extension of the structure atan angle of 45.

The hubs of the various connecting-members are provided with openings it through which shafts may be inserted, the openings of the auxiliary connecting-members for this purpose registering with the openings of the main connecting-member when the parts are assembled as described.

It is obvious that in place of the angles of.90 and 45 SllOWILlIl the drawing, other angles may be adopted, and that various changes may be made in the construction without departing from the spirit of the invention as set forth in the claims.

I claim:

1. A connecting-member for a toy building set, comprising a hub, plates spaced apart at each side thereof. and having outwardly-turned flanges at opposite sides of the plates, and a channel-shaped auxiliary connecting-member having lugs spaced apart and inserted in and frictionally rewhen used in connection with the other a memes e'y seidfianis, each m said mema my buildletes spaced havin out- -werdiy-tnrned flanges at opposite si es of the plates,

9. channel-shaped auxiliary conneci mg-memiser having; iugs spaced apart and. inserted in and frictioneiiy retained by said flanges, each of said members being pro- 'ided with slots at their respectivmsides, outwardly-turned flanges onthe auxiliary conneeting-member, and a second auxiliary connecting-member having lugs engaged one with one cf the ings of the main connectingmember and the other with one of the in of the fi st auxiliary connecting-member, and provided with oppositely arranged pistes hai ing siois therein.

3. cenneeting-member for a toy building set, coznnrising a. hub, plates spaced apart as each side theeeof and having outw i turned flanges at opposite sides of 1, gietes, e channei-sheped auxiliary con- Tzith siotsnttheir remeeting-member having iugs spaced apart and inserted in and irrationally retained by said flanges, each of saidmembers being provided with slots at their respective sides said connectingmember being provided in its hub with a transverse opening and said auxiliary member being provided with an opening registering therewith.

4. A connecting member for a toy build- 7 ing set, which has intermediate members, comprising a hub, plates spaced'epart at each side there H, 1nd an auxiliary connecting member having a face, and projecting members at right angles thereto, means for engaging said face and: said plates, and means on said plates and on said members for engaging with the intermediate members of se other and the toy building in testimony whereof I aiiix my signature in the presence of two witnesses.
